How we perceive the taste of bitter foods -- and whether we like or dislike them, at least initially -- depends on which versions of taste-receptor genes a person has, according to a researcher in Penn State's College of Agricultural Sciences. Those genes affect dietary choices, such as whether we eat enough vegetables, drink alcoholic beverages or enjoy citrus fruits. "Just like some people are color blind, some people are taste blind and simply can't taste bitter things that others can," said John Hayes, assistant professor of food science.
